An edge clamping head 330 is integrally provided on the outer wall of the lower insertion cylinder 310, and an edge clamping groove 331 corresponding to the edge clamping head 330 is provided on the inner wall of the lower insertion slot 311. Through this design, it is convenient to perform preliminary limit clamping when the lower insertion cylinder 310 and the lower insertion slot 311 are inserted, and the docking is relatively tightly sealed, making subsequent use more convenient;

[0027] More specifically in this embodiment, a lower insertion strip 340 is integrally provided on the side of the lower end of the middle splicing column 300, a lower clamping groove 341 corresponding to the lower insertion strip 340 is provided inside the side of the upper end of the middle splicing column 300. A lower insertion strip 340 of the same kind is integrally provided on the side of the bottom of the upper column body 200, and a lower clamping groove 341 of the same kind is provided on the side of the top of the lower column body 400. Through this design, when the lower insertion cylinder 310 and the lower insertion slot 311 are docked, it is convenient to synchronously drive the lower insertion strip 340 to be inserted into the lower clamping groove 341 and clamped tightly, facilitating the stability of splicing;

[0028] More specifically in this embodiment, the three lower insertion strips 340 are distributed in a triangular shape, and the three lower clamping grooves 341 also correspond to be distributed in a triangular shape. Through this design, it is convenient to provide limit support during clamping connection, avoiding relative rotation between the middle splicing column 300, the upper column body 200 and the lower column body 400, making the assembly connection more stable and not easy to shake;

[0031] Working principle: During assembly and use, according to the length of the photovoltaic fixing component and the required support column, the upper column body 200, the middle assembled column 300, and the lower column body 400 are spliced to form an alumina support 100 of the corresponding length. And during the production of the alumina material, it is convenient to prevent the generation and conduction of static electricity, making subsequent use safer. According to the required length and height, select the corresponding number of middle assembled columns 300 and splice them between the upper column body 200 and the lower column body 400, and then dock them from top to bottom in sequence. With the cooperation of the lower insertion cylinder 310 and the lower slot 311, it is convenient for initial limit insertion during up and down docking. Subsequently, with the cooperation of the bottom convex ring 320 and the bottom ring groove 321, it is convenient for limit support and relative sealing at the bottom of the docking part. Subsequently, when the lower insertion cylinder 310 is inserted into the lower slot 311, through the clamping of the side clamping head 330 and the side slot 331, it is convenient for initial limit clamping of the lower insertion cylinder 310 and the lower slot 311. Further, during the downward insertion process, the lower slot 341 cooperates with the upper end top slot 343, so that the lower insertion strip 340 enters the lower slot 341 during downward insertion. When the insertion is in place, the bottom hook of the lower insertion strip 340 is clamped at the bottom of the lower slot 341, so that the clamping connection assembly is completed. At the same time, with the triangular distribution of the three groups of lower insertion strips 340 and the lower slots 341, it is convenient to maintain horizontal stability and not easy to rotate. With the provision of the chamfer 120 and the groove 130, it is convenient to keep the end of the alumina support 100 round and not easy to cause scratches, making the operation safer and more convenient. The support column thus formed is convenient for cooperating with the installation of the photovoltaic panel fixing component. The operation ends here.
